Procedure
- Using a polymeric tubing cutter, cut the ends of a 0.6 m (2 ft) length of red PEEK tubing so that they are square.
IMPORTANT
Poorly cut tubing can cause flow restrictions.
- Make sure that the PEEK tubing is not crimped, kinked, or otherwise damaged.
- Connect the PEEK tubing so that it contacts the bottom of the LC union’s 10-32, coned-bottom receiving port.
IMPORTANT
Tubing that is not properly seated can add dead volume to a chromatographic system.
- Tighten the PEEK fittings using only your fingers. Overtightening the PEEK fittings can cause leaks.
